2023 Marathon Nationals

The Top O' Michigan Outboard Marathon National Championship race will celebrate its 75th anniversary in 2023.
Founded in 1949, the race which is known as the world's toughest outboard marathon, has grown to legendary status in the boat racing world. For more than 70 years, boat racers from across the United States, as well as other countries, have been coming to northern Michigan to race across the rivers and lakes of the Inland Water Route in an adventure that tests both drivers and their boats.
For an event to reach its 75th running year is impressive. There have been many changes over the years ranging from the course layout to the registration fees – but one thing is still the same – the passion.
This year, in accordance with celebrating 75 years of boat racing, there will be a few more events put in place along with the club upping their usual customs. There will be over $8,500 awarded to top finishers and National Champions, bigger trophies, new merchandise and apparel, tons of freebies, two MORE parties, and a few surprises.
If you’ve been on the fence about participating or attending, now is your chance! This year will be bigger and better than ever, that we can promise.
